    A method of, and apparatus for, grinding cutting tools attached to a cutter head for gear cutting machines, the cutter head having sets of cutting tools encompassing three respective groups of cutting tools, specifically inner cutters, outer cutters and auxiliary cutters. Two groups of the cutting tools are removed from the cutter head, the first group of cutting tools is completely ground at the cutter head, the second group of cutting tools is inserted into the cutter head and completely ground, and then the third group of cutting tools is inserted in the cutter head and completely ground.

    (St) METHOD OF GRINDING KNIVES OF CUTTING HEAD AND MACHINE FOR SHARPENING
    one
    The invention relates to metal cutting and can be used for sharpening tools, such as gear cutting heads.
    A known method of grinding knives of a cutting head of a gear grinding machine for machining gears with a circular tooth, having a set of internal, external and auxiliary knives arranged in rows, consists in installing the tool on a grinding machine and machining each tooth by individual grinding 111.
    A disadvantage of the grinding method is that the processing takes a lot of time and the sharpened head has low accuracy.
    A known machine for sharpening a tool, comprising three grinding heads with an individual rotation drive and mechanisms for the individual movement of the heads 2. TOOLS
    The disadvantage of the machine is that it has low productivity, since it is inconvenient to handle the cutting head knives on it.
    The purpose of the invention is to reduce processing time and improve processing accuracy.
    The goal is achieved by the fact that, according to the method of processing, grinding is conducted in the bottom, and
    The 10 cutting heads preliminarily remove two inner rows of knives, and after grinding the outer row and a follower, the others are set and ground.
    15
    The processing machine is equipped with a rotating disk on which grinding heads are mounted with the possibility of radial movement.
    In Fig.1, a machine for sharpening a tool head is shown schematically.

    [1]
    The sharpened gearing head 1 (Fig. 1) consists of several sets of knives 2,3 and each of which has an outer 5 and an inner 6 flange and a front edge 7. The distance from all three knives to the axis of the 0-0 head is different and respectively, Gd; The arrangement of the knives is equal to r, r2, on the gear-cutting head, such that the processing of a complete set of them is fraught with considerable difficulty. Sharpen gearing head 1 is mounted on the spindle product 8 (Fig 1.2 and 3) of the headstock E installed n) and the frame 10 supporting the body 11 with a rotary shaft on which the disk 12 is mounted, Grinding heads 13 I and 15 are mounted on the disk 12 with the possibility adjusting displacements depending on the parameters of the gear cutting head. Grinding heads 13, H and 15 with abrasive wheels 16, 17 and 18, respectively, serve to sharpen the outer 5, inner 6 flanks and front faces 7. The axes of the grinding heads lie in planes parallel to the axis 0-0 of the spindle of the product, the projection which on these planes is with the axes of the grinding heads 13 and I an angle i, an angle of 90 ° with the axis of the grinding head 15. There is a recess 19 on the disk 12, facilitating access to the gear head. The device works as follows. The disk 12 is mounted against the spindle of the product 8 by a recess 19. On the product spindle 8, a gear head is fixed with one row of knives. Then the disk 12 is rotated so that the abrasive wheels 16 and 17 are opposite the knife to be sharpened, while 15 is pre-adjusted to the parameters of the sharpened gear cutting head 1. By moving the headstock 9 in the direction of the disk 12, the working feed is carried out. Thus, the outer 5 and inner 6 flanks are simultaneously sharpened with abrasive wheels 16 and 17. After the first knife is sharpened, the headstock 9 moves to its original position, the spindle of the product 8 with the head 1 turns with an angle equal to the angular pitch and cycle sharpening the outer and inner flanks is repeated. After the flanks of all the knives of this 9 4 row are sharpened, the disk 12 rotates, so that the abrasive wheel 18 sharpens the front edge 7 opposite the knife. The working feed is carried out as in the previous case by moving j6a6ki 9 in the direction of the disk 12 After sharpening along the front face of the first tooth, the headstock 9 moves to its original position, the spindle of the product 8 with the gear cutting head 1 is rotated at an angle equal to the angular step, and the sharpening cycle of the front edge of the next knife is repeated. After the first row of knives of the gear cutting head has been completely processed, the disk 12 is rotated so that the recess 19 is located opposite the head 1, then the next row of knives is mounted on the gear cutting head, and the sharpening cycle is repeated. After the gear-cutting head has been completely processed, it is removed from the device, a new one is installed on the spindle 8, and the cycle is repeated. Processing the blades of the cutting head according to the proposed method and on this machine allows increasing productivity and accuracy of processing. Claim 1. A method of grinding knives of a cutting head of a gear grinding machine for machining gears with a circular tooth, having sets of knives for internal, external and auxiliary, is arranged (in rows, consisting in installing the tool on a grinding machine and machining each tooth by individual grinding, characterized by that, in order to reduce the time for processing and increase the accuracy of processing, grinding leads to the bottom, and two internal rows of knives are preliminarily removed from the cutting head, and after the outer rows are sequentially installed and polished the rest, 2. The machine for sharpening the tool, including three grinding heads with individual rotational drives and mechanisms for the individual movement of the heads, is different, in order to increase productivity, it is equipped with a rotating disk, on which grinding heads are installed with the possibility of radial movement, Sources of information,... taken into consideration; not during examination 92Н 5 6 1.
